Hi,
I'm new to home recording. Following is the list of my current hardware/software.

- KN7000 keyboard connected to laptop (P4, 3GHz, 512MB RAM) via USB
- Roland VA-7 keyboard connected to KN7000
- Acid Pro 5 software.

I've recently put together some drum loops into Acid for a song. I want to add strings, guitar e.t.c from the keyboards and maybe some vocals. Follwoing are my concerns.

1- Since i don't have a mixer, i can not monitor the drums playback while i add/record tracks from keyboard or the worst, add vocals using mic input in KN7000. Do i really need a mixer to do this ?

2- If YES, which mixer?, i'm looking into Yamaha's o1x, but have heard a lot about mLan issues. Any suggestions ? My other concern is if o1x would let me control Acid Pro 5 from the control surface ?

3- What is the practice in pro recording world, should you always record from a workstation synthesizer with digital outputs or you can record from a keyboard like Roland VA-7 using 1/4 pin analog connection ? The reason i'm asking this is, because i'm thinking maybe i should sell the two keyboards i have and buy one which would give a digital interface. (even though KN700 has USB interface but i don't like its voices as compared to VA-7).

awaiting for help/comments..

farhan.

Well, Farhan, you've asked many, many questions. Let me try to answer some of them as good as I can from my point.

If you're recording a track from your stereo line in plugs of your sound (or better audio) card then you can be accompanied by a stereo track from your harddisc at the same time. Your Windows OS has a little mixer for the sound card to mix the sound sources together to one output plug.
Well, using a professional studio software means you're having more options to mix and record tracks. Look into your software manual how to switch ins and outs for your song - be it audio or midi.

It's very professional to spare data space as much as possible. If you're using real hardware synths then you're able to record midi tracks which will control your hard synths in real time. So, you can create all sounds again and again without the necessity to record it as an audio track.
Remember: One minute stereo wave sample at 16bit/44.1kHz needs 10MB disc space but a whole midi arrangement with 16 midi channels programmed and up to 20 minutes playtime keep it under 200KB.

IMHO audio tracks are needed right in that moment when you're recording sounds with natural curves (for example: chorus, flanger, phaser) or instruments with natural attacks and decays by the player's fingers (for example: voices and all analog instruments).

Personally, I tend to use analog mixers for ADD recordings. If you're mixing it digitally then you'll become many problems with actual computer standards. We still have a 16bit/44.1kHz recording standard but at the moment we're going streight into a 24bit/96kHz recording era. Oh no!!! The next standard can be seen at the horizon - 24bit/192kHz! And I guess there will be no end for this death spin...
Digital recordings will never reach towards the analog quality especially for mastering!

Well, I hope I could help you a little bit. I wish there will come some more opinions by other SynthZone members to mix some other colours into this thematic...

Greetings farhan!

It is always a good idea to use an analog mixer for all kinds of studio recording. Doesn't matter if you decide to record all the tracks to your hard disk individually (to later mix them in a digital domain using software like Sonar or Cubase etc) or mix them in an analog domain and then bounce to a stereo track (Will save hard disk space) to Acid or whichever audio software you decide to use. Again, if you're not pressed for hard disk space it is not an issue.

A good analog mixer is a must have if you plan on recording hardware synths and acoustic instruments or vocals.

Personally I mix in both digital and analog domains without any issues or problems. There used to be some issues with digital recording and editing but that is really a thing of the past. I've been recording, mixing and mastering digitally for roughly over 10 years and it was great than and is just getting better. With your 3Ghz laptop, a decent audio card and some good software you will not have any real issues worth panicing about . Most here wil agree with me on that. If you had an older computer and a crap interface with bad ASIO support and software compatibility issues then yeah. It would suck. Not your problem though. and so on

Less of that though. It is really just a matter of preference. Put it that way. I record all of my acoustic instruments/ vocals into my G5 via MOTU 828 at 24 bit 48 or 96k but for my hardware synths I mainly use analog mixing (unless of coarse I need to process the **** out of some sounds using plug-in FX ) and it works out great for me. It really wouldn't make sense for me to record all of my hardware digital and analog synths into my Mac individually to then basically end up doing what I can pretty much do in an analog domain. Thus the answer to your question of the "professional standard procedure" regarding the use of Digital I/O in studios. Most hardware synths can be recorded using MIDI, mixed using an analog mixer and than mixed down to your DAW. There are some studio devices which do require the use of Digital I/O but really, there are too few to worry about. For you anyway.

Of coarse if you were to use software synths and instruments the wise thing to do would be to mix digitally since redunndant A/D conversion and extra math would only take away from the sound. However, I'm known for doing weird shit like running my software Oddity or Pro 53 through real tube preamps and guitar/bass amps to add a different character to the sound. But that's just me.

Mixer wise I can only recommend what I've been using myself for as long as I remember. Right now I use two Mackie 12/02 mixers as my "mixer-mixers", a slightly older 16/04 and a used SR-24. All are great. I'm maxed out on my inputs. Because I'm nuts and I have too much stuff here. In your case you'll be quite happy with something like a Mackie 12/02. It's got 4 stereo inputs (l/R each), two FX sends, 4 mic preamps (or XLR balanced ins if you wish to use them that way) an alternate 3-4 bus to basically rout any channel to (to then go directly to your DAW inputs) and four inserts (never used them myself). THere is a 3-band EQ per channel (or stereo channel). Mackie bass EQ drops below 80hz which is pretty good for low low basses. Most mixers don't fall below 100hz when it comes to bass EQ. In overall it's a good little mixer.
Mind you there are other good mixers out there too but since I haven't got any personal experience using them I would prefer sticking to what I know.

So that was my $00.02 for ya. Good luck with your stuff.
